hey guys, i just picked up this 86 civic hatch 4-speed with the 1.3l carb'd. I have never worked on a crab'd engine before so i need some help. The car only has 69K miles on it and the owner said it ran fine. I have just put about 100 miles on it and the car started to not run right. The car would ahve no throtle response so i would down shift into high rpms and the car would then run alright. When i can to a stop the car then died. it would start back up but at the next stop the car would stall again. Went to school and car started to act up when i pulled into the parking lot and kept stalling out. after school went to start up the car, it would start and then stall. with a pratial throtle the car would not stay running. it just keeps stalling out. New parts installed: fuel filter, air filter, plugs, wires, dizzy cap and rotor. got it towed home, so now it sits. what could be making my car not run. thanks and sorry for the long post. I also searched around and posted on redpepperracing but no response. thanks for the help

how long was the car sitting before you bought it? the carb could be clogged up a bit

 

i had an 85 hatch 1.3L carbed with 4 spd tranny.

did you replace both fuel filters? There's one near the tank and another in the bay.

 

the guy told me that they drove the car "some" i believe that there had only been 1000 miles or less since april. I only have one new fuel filter, but there is two in the engine bay. one small and one bigger? the car ran fine when i test drove it, drove it home, drove it around all night, and the next day. then it started to not run right. i will try and replace both of the filters, if not i might just havce to take it down the street to the local mechanic, which i dont really want to, but oh well. thanks guys

it's been yeaars since i've changed those filters. Sorry i don't remember the sizes..iirc there's one in the bay near the distributor. The other is located behind the left rear wheel, under the gas tank.

 

alright ill take a look

 

bump

 

up

 

Get the shop manual for the car. Tearing down and rebuilding carbs is pretty strightforward. Sounds like you have a clogged pilot jet, it controls your idle. They are really small, when you take it apart use a wire to clean the jets, an E string from a guitar is usually a good size.

thats what i was thinking, because it had been sitting the gas has gummed up and clogged the carb

it's not that straight forward, for the most part. civic's have about 40-50 vaccuum lines to deal with when taking off the carb.

check out redpepperracing.com they'll give you a lot of help there. that's where i learned to tune the 1.3L CVCC EJ1 in my 82.

if it comes to the point of having to rebuild the carb, you're better off a) replaceing the engine, or b) getting a mounting plate and setting up some webbers.

 

I've only worked on carbed bikes, and they are pretty simple. Fuji, what colour is your CVCC? I'm at RPI in Troy and I've seen a maroon one a couple of times in the parking lot at Latham Farms. Looked really clean, my roommate didn't understand why I was so excited over an original civic.

 

that's prolly mine, i've got one of the only ones in the area. it's brown. i just had my twin loop welded up on it this morning.

i brought it to many of the car shows and the honda-tech meet this summer...

 

replaced both of the fuel filters. after a bit it started up and ran, idled for about 5 min, gave it a little gas let off and it stalled. its now doing the same damn thing.... what can be wrong?????

you have a clogged carbureator man, you need to clean out the carb. its gonna be a bitch

 

i used a ton of carb cleaner on it. from the looks of it, it appears to be clean. any way to clean futher without taking it off.... why so many vac lines??????? damn honda carbs. fi&gt;carbs

 

i dunno how different or complicated a honda carb is compared to anything else, but I bought an Edelbrock carb off ebay for my camaro, and it ran decent for awhile, but after a couple months it started to crap out so i went out and bought the rebuild kit, and without any other experience besides my mini bike carb i just followed the instructions carefully and rebuilt that sucker (there was ton of leaves and crap all along the main tube in the back of the carb, so only one side was acctually getting a good amount of fuel) and it ran beautifully the first time, i was so proud because it only took me about an hour or so to do it. then again i only have 2 vacuum lines and four bolts, the aircleaner nut and the brake vacuum line to get to the carb, i could understand how the honda's BS emissions would be annoying. if anything i noticed someone said it would be worth it to replace the engine if the carb is bad. that is probably the worst advice you could take, because if worst comes to worst and rebuilding it doesnt do the trick, replace it with a reman and if that doesnt work THEN look into a mechanic to do it professionally, stil dont replace the engine.

 

i called a lot of the local mechanics and they don't work on carbs???so i might just try to find a way a replace it. the only bad thing is there are about 30-35 vac lines on the damn thing.

 

as for cleaning the carb, you cant just clean the unit itself, you also need to clean the jets as those get clogged as well

This is probably the biggest problem with working on later model carbed cars. When the governmemt started to crack down on emissions, carburetors became EXTREMELY complicated. The miles and miles of vacuum lines under the hood look intimidating indeed. All I can say is that when I saw my brother's old carbed CRX, the last thing I wanted to do was touch it! Thank God for fuel injection!
